中文摘要：

目的：对海南龙血树所产血竭的化学成分进行研究。方法：运用硅胶柱色谱和SephadexLH-20凝胶柱色谱等方法对化合物进行分离纯化,通过理化性质及波谱数据鉴定其结构。结果：分离鉴定了8个化合物,分别为丁香脂素（1）,松脂醇（2）,蛇菰宁（3）,2-（4-hydroxyphenyl）-6-（3-methoxy-4-hydroxyphenyl）-3,7-dioxabicyclo[3.3.0]octane（4）,5,7-二羟基-4′-甲氧基-8-甲基黄烷（5）,7,4′-二羟基-8-甲氧基高异黄烷（6）,（2R）-7,4′-二羟基-8-甲基黄烷（7）,（2S）-7,3′-二羟基-4′-甲氧基黄烷（8）。结论：以上化合物均为首次从海南血竭分离得到。

英文摘要：

AIM： To investigate the chemical constituents from dragon′s blood of Dracaena cambodiana in Hainan. METHODS： Compounds were purified by silica gel and Sephadex LH-20 column chromatography, and their structures were identified on the basis of physicochemical properties and spectroscopic data. RESULTS： Eight compounds were isolated and identified as syringaresinol （1）, pinoresinol （2）, balanophonin （3）, 2-（4-hydroxyphenyl）-6-（3-methoxy-4-hydroxyphenyl）-3, 7-dioxabicyclo[3.3.0]octane （4）, 5, 7dihydroxy-4′-methoxy-8-methylflavane （5）, 7, 4′-dihydroxy-8-methoxyhomoisoflavane （6）, （2R）-7, 4′-dihydroxy-8-methylflavane （7） and （2S）-7, 3′-dihydroxy-4′-methoxyflavane （8）. CONCLUSION： Compounds 1-8 were reported from the dragon′s blood of D. cambodiana for the first time.
